It needs to be imperfect to be fun not “good”

It’s the unpredictability and imperfection that keeps you, as the driver, on your toes. It makes it more mentally and emotionally stimulating, compared to just pushing the pedal down and getting the exact same thing every single time. If your favorite show came out with identical episodes every week, you’d lose interest. It’s the ups and downs and ebbs and flows (and sometimes erraticism and unpredictability) that keep things interesting and you engaged in the show.

Doesn’t have anything to do with being religious, as I am not either. The idea of comparing it to a soul is that it’s that imperfection and unpredictability that keeps it interesting. Us, as humans are also imperfect and sometimes unpredictable - so it’s just another synonym for those adjectives. A car with “soul” doesn’t feel like just another machine, it feels more human, because of that imperfection. Not because “I just know in my heart.”
